Diaz threatened to wreck Pochettino's first competitive encounter in command of the Blues in the 18th minute, as the Colombian reached out a boot to turn in a defence-splitting cross by Mohamed Salah as the visitors attacked with lightning pace.
Just over 10 minutes later, Liverpool felt it had increased its advantage, but Salah was adjudged to be offside before putting the ball past goalkeeper Robert Sanchez, one of four debutants in Chelsea's starting lineup.
After surviving the first shock, Chelsea levelled in the 37th minute after Liverpool failed to clear a corner, and France international Disasi—who had recently been signed from AS Monaco—kicked the ball in from close range following a looping header from Ben Chilwell.
When Chilwell attempted to score after going around Alison Becker in goal, VAR judged he was offside.
After halftime, Chelsea controlled possession but failed to score a second goal. A deflected shot by substitute Darwin Nunez in the latter moments nearly gave Liverpool the victory.">
